Specification of Letters Patent. 1331391111561 June 27, 1922.

Application filed September 16, 1919. Serial No. 324,215.

To au whom t may concern:

Be it known that I, ARDHENDU BHUSHAN SINHA, a subject of His Majesty King George V, King of England, residing at Muzaffarpur, British India, and whose address is care of The Bengal Preserving Company, Muzaffarpur, British India, a vakil of the high court of judicature at Fort William, in Bengal, have invented an Improved Wagon Seal, of which the following is a specification.

The object of this invention is the provision of an improved seal for fastening railway cars and the like.

A reliable means for sealing railway cars is most necessary and the provision of'a seal which cannot be tampered with without showing distinct traces of such tampering is very essential.

I employ the following means to attain this end. A strip of thin sheet tin about 14 inces long and lgA inch wide is used. A hole with rough edges is pierced through this strip at one end. Into this hole a rivet formed of lead or other suitable plastic material is fixed. The rough edges of the hole or the burrs formed by the punch help to grip the shank of this rivet and hold it in place. At the middle of the length of the strip and at its further end other holes are punched. These holes are cleanly punched, leaving smooth-edged circular holes about of an inch diameter each. A washer formed of lead or other suitable plastic material is soldered or otherwise fastened to the strip, the hole in such washer being in line with the cleanly punched hole in the end of the strip. This washer is fixed to the opposite side of the strip to that from which the head of the lead rivet, previously referred to, proiects.

In fastening the car the strip is bent into an S shape, the two ends being brought together at the centre. The shackles or handles of the car doors lie in the two loops or in one of' the loops, the` other loop being utilized to hold a tag or label. The projecting shank of the rivet is then pushed through the hole in the centre of the strip and finally through the hole and washer at the other end of the strip. A sharp pressure from the sealing instrument then closes the seal riveting the projecting shank of the rivet to the washer and impressing it with the code initials of the station.

My device is illustrated in the accompanying drawing in which like letters of reference indicate like parts throughout, and in which Figure l is a part section of one of the strips with the rivet and washer attached;

Figure 2 is a part elevation of the same;

Figure 3 is a section showing the seal when closed down; and

Figures l and 5 show enlarged views of two shapes my washer may take.

In these figures, the strip a is pierced with clean cut circular holes Z) at the centre, and c at one end. The rivet (Z passes through a roughly pierced hole e at the other end of the strip, its shank f projecting through the strip. A lead washer g is fastened to the strip opposite the hole c. l

In fastening the car doors the strip is bent as shown in Figure 3 around the door handles or shackles h lz, and closed down as shown.

It will be readily understood that I do not confine myself to the exact arrangement described or illustrated but claim any reasonable modifications of the same. For instance, although I use strips of tin because I find this the most convenient material, I may use any material I like for these strips. Again, although I use a soft type of lead for the rivet and washer, I may use any other soft plastic material. I generally find it best to make the wsher also of lead, but if I prefer could make is of a non-plastic material. It might have a rough or serrated edge or surface to form a better key7 for sealing the head of the rivet to. Such key would also make tampering more difficult. The exact length shape or size of the parts is of course immaterial.

I claim 1. Seal for railway cars and the like comprising a strip of flexible material having holes, one provided at each end of the said strip and a third hole intermediate the ends and arranged to be brought in register with each other, a rivet of plastic material extending through one of the end-holes and adapted to pass through the other two holes to be thereafter formed into a seal, and a Washer of soft metal attached to the other end of the strip surrounding the hole at that end so as to receive the pressure of the seal.

2. A seal for railway ears and the like comprising a strip of thin sheet tin having at one end a hole with rough edges a rivet of lead fixed in this hole, a Washer of lead attached to the other end of said strip and having a hole registering with a hole at that l0 end.

In testimony whereof I hereto aix my signature in the presence of two witnesses, this 7th day of August, 1919.
